Yes, the first flat screen TV was actually introduced in 1958, but that's not the only strange invention you'll find in this blast from the past.

Flying Saucer Camera

This "Flying Saucer Camera" was first introduced back in 1953 and was designed specifically for the Air Force. It featured one lens to "take regular pictures" while the second lens "separates light into colors so scientists can judge the source and make-up of saucers".

Clock Phonograph

Similar to the CD player alarm clocks we have now, this device offers a built-in phonograph that "awakens you in the morning to the sound of music". The "Clock Phonograph" was first shown in a 1931 issue of Modern Mechanics.

Both phonograph and clock motor is contained in a box the size of a large camera, and the hour for the morning serenade is set by knob as in an alarm clock. When out of use the case is folded up to make a neat and attractive table or mantel ornament.

Wrist-Watch Radio - 1947

First introduced in 1947, this wrist-watch radio used a "new miniature radio transceiver being developed by the U. S. Bureau of Standards", capable of receiving/transmitting short waves while also picking up standard radio broadcasts.

This world’s smallest microtube was made possible by the elimination of bulky wires, which have been replaced by a silver chloride circuit stenciled on a slice of plastic or ceramic material. Developed as a result of co-operative research with industry, the miniature tube has various military applications aside from its use in the wrist-watch radio

14 Ton Camera - 1934

Two years’ time was needed to build the camera which can take photographs with microscopic exactness. It is equipped to make nautical and airway charts with a precision of less than l/1000th of an inch. The camera can hold plates as large as 50 inches square.

Flat Screen TV

According to this old Popular Mechanics article, flat screen televisions have been around since 1958 -- or at least the technology. Designed mainly for military use, it just never caught on due to patents/licensing issues.

The picture tube, only 2-5/8 inches thick, is made of two rectangular pieces of plate glass with about an inch of space between them. The edges are sealed with powdered-glass solder to hold the vacuum. The surface of the thin tube is the equivalent of a 21-inch conventional screen
